The OEM belt is a Unitta and made in Japan. Gates-Unitta seems to one company though. I know on some Honda's they have "Gates" clearly printed on the belt but not on ours.

Only problem is the OEM one is double the price. ~120$

Lightbulb Re: Gates timing belt kit? As good as OEM?

If Gates is not the OEM, I like the blue racing timing belt for my Subaru synchronous belt cam drive. Gates rates it equal to and better than OEM and often such claims should be taken with a grain of salt and consider going with OEM if not a proven product.

Belts can be made of different cord materials, jacket materials & coatings, and rubber material. When I learned Gates racing timing belts are made of EPDM rubber, use aramid cord (generic name for Kevlar), and use teflon impregnated jackets for the tooth side I knew to use this belt regardless of OEM. This construction was originally developed to last longer than chain systems, plus stretch and wear less than chain.

Unfortunately automakers elected to go more with chain 10-15 years ago as the chain suppliers had greater influence as many supplied transmissions and other high end OEM parts influencing engine designs having even some new generation Honda, Toyota and others go to chain systems. Belts for cam systems suffered from historic technology baggage due to older belt constructions baggage while the best timing belt ever was developed by Gates to-date specifically to last the life of the engine 10+ years, 150,000+ miles.

Others like Dayco used teflon on their white belt, much has been duplicated but the Gates construction, like a secret recipe, is the one that makes either the OEM caliber or better belt, if it is the EPDM, aramid, teflon jacket version. Of course they make various other constructions and that is the basis for how well most timing belts perform. OEM's will always charge more since they are the OEM.

I'm putting a Gates Racing Blue belt (EPDM rubber, aramid cord and teflon jacket) on my 2.5L turbo cam drive and do not plan to change the timing belt ever again. I will be checking it though for cracks, wear, and modulus/stiffness to feel if the cord is fatigued after 100K miles and every 30K-50K after that just to make sure.

Gates and Unitta share some technologies with tensioners and belts coming up with an agreement to work together to give each other presence in other global regions (eg. Gates in Japan).

The Gates Racing blue timing belt may be better than OEM for Honda. Many OEM Honda belts were made by Gates in the US for Honda.

I am planning my timing belt replacement on 2014 STI. Just reached 80k. Doing research on cost and quality

Trying to do apples to apples comparison with OEM and Gates kits. I did not see any vendor selling an equivalent kits to the Gates Timing Belt with Water Pump kit on RSD, so here is my research as of March 2017 for 2014 STI from the cheapest dealer website.
  • Timing Belt 13028AA250 ($97.17*1=) $97.17
  • Belt Tensioner 13033AA050 ($98.46*1=) $98.46
  • Idler Pulley 13073AA230 ($49.22*2=) $98.44
  • Idler Gear 13085AA080 ($56.20*1=) $56.20
  • Water Pump 21111AA240 ($94.58*1=) $94.58
  • Thermostat Unit 21210AA030 ($19.41*1=) $19.41
  • Thermostat Gasket 21236AA010 ($2.22*1=) $2.22
Subtotal $466.48

vs


Gates Timing Belt Kit with Water Pump (sourced from RSD) TCKWP328 $234.00
1 Timing belt
1 Hydraulic tensioner
4 Idler pulleys
1 water pump w/gaskets
1 Thermostat gasket

Plus
Subaru OEM Thermostat SUB 21200AA072 $21.95

Subtotal $255.95


so is OEM parts almost double the cost worth it?
